Log information extraction method and device, computer equipment and storage medium

Abstract

The invention relates to a log information extraction method and device, computer equipment and a storage medium. The method can be applied to various scenes such as cloud technology, artificial intelligence, intelligent traffic and auxiliary driving. The method comprises the steps of obtaining to-be-processed log information, historical log information and a pre-stored historical keyword set, wherein the historical log information comprises historical keywords; performing feature extraction on the historical log information to obtain a public feature parameter set corresponding to the historical log information; filtering the to-be-processed log information according to the public feature parameter set and the historical keyword set to obtain preliminarily filtered log information; determining a longest common substring corresponding to the preliminarily filtered log information by adopting a longest common substring algorithm; and filtering the to-be-processed log information according to the longest common substring to obtain target log information. By the adoption of the method, the log information extraction efficiency can be improved on the premise that no specific keyword exists.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a log information extraction method, device, computer equipment and storage medium. Background technique [0002] With the development of computer technology, log information extraction technology has emerged, which is mainly used to extract effective information in system logs, so as to use effective information to analyze and process the system. [0003] In traditional technology, due to the different ways of printing logs between systems, common keywords cannot be used to filter system logs. Therefore, it is necessary to set specific keywords by yourself when extracting valid information in system logs each time. [0004] However, due to the need to set keywords one by one every time valid information is extracted in the traditional method, the operation is cumbersome, and there is a problem of low efficiency of log information extraction.
